摘要

PROBLEM TO BE SOLVED: To provide a method for executing shot crete grating crib works, which can reduce executing costs without damaging excellent performance such as strength and durability, and to provide a reinforcing bar support member for use in the method.;SOLUTION: A lath folding type reinforcing bar support body A is obtained by swingingly pivoting a reinforcing bar support frame 5 having a cross portion 6 and a self-supported bar leg 7 downwardly formed at the outer edge, via a pivoting portion 4 on a single surface of a lath wall surface body 3. The support body A is arranged on a lath net 2 stretched on a slope surface 1 at a location where grating crib is formed, such that the lath wall surface body 3 is deflected on one side of a longitudinal grating crib 11a in a direction of the longitudinal grating crib 11a and deflected on a lower slanting side of a transverse grating crib 11b in a direction of the transverse grating crib 11b. Each reinforcing bar support frame 5 is opened, and the self-supported bar leg 7 is pierced into the slope surface 1 to be self-supported. Then, the bar leg 7 is brought into contact with the cross section 6 of the reinforcing bar support frame 5 to pierce a reinforcing bar 8. Further, the bar leg 7 is fixed to each cross section 6 by a fixing member 9, and then concrete 10 is shot such that the entire reinforcing bar support body A and the reinforcing bar 8 are covered therewith.;COPYRIGHT: (C)2001,JPO
